Answer:

75% of the planets have moons

Explanation:

In order to calculate this you just have to do a simple rule of three, in which you will use 888 as the 100 percent and you want to discover what percentage of that does 666 represents:


(888)/(100) (666)/(x) \\x=(666*100)/(888)\\ x=75\\

So you have that 666 is the 75% of 888, that means that 75% of the planets have moons.
